Reported: 2025-05-30 (May 30, 2025)
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2024 GLE 350 4MATIC, 2025 GLE 450e 4MATIC, GLE 450 4MATIC Coupe, GLE 450 4MATIC, GLS 450 4MATIC, Maybach GLS 600 4MATIC, AMG GLE 53 4MATIC, AMG GLE 53 4MATIC Coupe, AMG GLE 63 S 4MATIC Coupe, and AMG GLS 63 4MATIC vehicles.
